A Dublin man who suffers from type 1 diabetes and has completed a triathlon hopes his success will inspire others with the condition.
Gareth Lee (39), from Donabate, previously confined his exercise to walking and never dreamed he would complete a triathlon of swimming, cycling and running.
As a diabetic, he has to take insulin and keep his blood-sugar levels under control. Exercise affects the blood glucose level, so the insulin treatment needs to be adjusted.
It allows for continuous glucose monitoring with the help of a small glucose sensor that he wears for up to six days at a time.
"I had also been suffering from depression and the exercise I was able to do also helped me to recover from the illness," said Gareth.
"If you had told me last year that I would have completed a triathlon I would have said you were mad."
It left him anxious all the time and stopped him from being as active as he wished. "Running was out the question," he added.
Gareth says while the device has worked for him, it may not be right for everyone and people with diabetes should discuss their options with their diabetes team.
Exercise is important for people with type 1 diabetes, but they need to monitor their glucose before and after to understand how it responds to activity.
